Claims.

The instant invention relates to building constructions, and, moreparticularly, to tools or devices for use in securing fastening elementsof the type disclosed incur copending' application Serial No. 439,036,filed April 15, 1942, of which the present application is acontinuation-in-part, and now Patent 2,351,994.

As pointed out in said copending application, heretofore attempts havebeen made to employ a sheathing material for building constructions, thematerial having relatively little ability to hold ordinary nails orother conventional fastening means. The copending application describesand claims one type of construction and method which is of particularadvantage in solving this problem, the method involving the use ofwire-like fasteners or nails which are driven through the shingle orother covering element and the sheathing material to extend asubstantial distance therebehind. The extending ends of the fastenersare wound into a coil bearing tightly against the rear face of thesheathing, whereby the covering elements are held against the sheathingunder yielding pressure and the fastener is prevented from pullingthrough the sheathing due to the presence of the coil.

Our present invention has for its principal object the provision of atool for use in the method of our said prior application. Y

Another object of the invention is the provision of an improved tool ordevice constructed to enhance the facility and speed with which thesecuring or clinching of the fasteners may be accomplished.

A still further object of the invention is the provision of a tool whichcan be operated efiiciently without the use of highly skilled labor.

Our invention will be more fully understood and further objects andadvantages thereof will become apparent when reference is made to themore detailed description thereof which is to follow and to theaccompanying drawing, in which:

Fig. 1 is a perspective view of a tool or device in accordance with theinvention;

Fig. 2 is a perspective view on an enlarged scale and with parts insection of the device of Fig. 1

Fig. 3 is a detailed perspective view on an enlarged scale of a portionof the apparatus;

Fig. 4 is a partial perspective and partial sectional view, illustratingone step in the use of the tool of Fig. 1;

Fig. 5 is a view similar to Fig. 4, illustrating a further step; and

Fig. 6 is a view similar to Fig. 4, illustrating a final step in the useof the tool.

Referring now to the drawing and, more particularly, to Figs. 1 and 2, atool in accordance with the invention comprises a shaft I0 connected toan operating handle 12 through the medium of transmission gearing l4carried in a cylindrical gear box IS. The free end of shaft I0 isprovided with a radially projecting slot l8 extending from the free endfor a substantial distance up the shaft. Slot 18 does not extendcompletely through the shaft, but is in the form of a recess with aclosed end or rear wall 20, and defines connected tines 22 and 24, thelatter being cut back a substantial distance to provide an open-faceflange 26 terminating in a right-angle flange or wall 28 formed as anextension of the rear wall of the slot. Preferably, the end of the shaftis tapered as illustrated.

The transmission gearing illustrated generally at I4 is preferablyarranged to provide for a plurality of revolutions of the shaft upon asingle rotation of handle [2. As will be understood, other suitablegearing or transmission means may be substituted for that specificallydescribed. As shown, the arrangement comprises a sleeve 30 connectingshaft I0 to a stub shaft 32 projecting from handle 12, both shaft to andstub shaft 32 being, preferably, freely rotatable in the sleeve.

Fixed to shaft I0 is a gear 34 and to shaft 32 is a gear 36. Gears 34and 36 mesh with larger diameter gears 38 and 40, respectively, carriedby and keyed to a countershaft 42 supported in suitable bearings in theheads 44 of gear box IS. The keying of the gears to their respectiveshafts prevents endwise removal of the shafts through the heads. Spacingring 46 may be provided between the heads and gears 34 and 36, ifdesired. The gear box includes a cover 48 fastened to heads 44 in anysuitable manner. As illustrated, preferably the heads 44 are circular toprovide a cylindrical gear box IS, the latter serving as a hand grip forthe workman in his use of the tool.

Referring now to Figs. 3, 4, and 5, the operation of the tool is shown.Shingles 50 are secured to a sheathing 52 by pins or other wirelikefastening elements 54, which are of such length as to have extendingshanks 56 projecting a substantial distance to the rear of thesheathing. When the fastening pins have been driven through the shinglesand sheathing as illustrated in Fig. 3, for example, the tool is graspedby handle l2 with one hand and preferably by the gear box It with theother hand and the end of 3 shaft I is manipulated until the extendingshank 56 rests on flange 26 (see Fig. 4).

The tool is then moved endwise, and laterally if necessary, to shift theend of the fastener shank against rear wall 20 and alon flange 26 untilit slides into groove I 8 (see Fig. 5). The shaft is then rotated byrotation of handle member I2, whereby the fastener shank is wound aroundthe shaft until the coil thus provided is in engagement with the rear ofthe sheathing 52. An extra twist is preferably given to the tool tobring the coil into tight engagement with the rear of the sheathing andto draw the head of the fastener firmly against the shingles and theshingles and sheathing into tight engagement with each other (see Fig.6).

Gearing M is, as previously stated, suitably arranged to permit multiplerevolutions of the shaft 10 upon a single revolution of handle l2.Preferably, the relationship between the gear diameters is such that,say, approximately a halfrotation of the handle causes two completerevolutions of the shaft. In the normal case, this will permit thecomplete clinching of the fastener shank without shifting the hand onthe handle.

As will be understood from the explanation of the operation of the tool,the particular flange and slot construction of the shaft permits theeasy engagement of the tool with the fastener shank. In the event that afastener is closely adjacent to a stud or other framing member to theright of the fastener, the tool may be held in the reversed position andbrought downwardly onto the shank until the flange 26 rests upon theshank end. In either case, no great degree of skill is required tomanipulate the tool for rapid and efiicient operation.

Having thus described our invention in rather full detail, it will beunderstood that these details need not be strictly adhered to, but thatvarious changes and modifications will suggest themselves to one skilledin the art, all falling within the scope of the invention. as defined bythe subjoined claims.
